A very clear evening resulted in me being able to split this one tonight (I had tried previously, but no success). Faint but distinct companion visible. PA about 300 degrees. Main component is a little reddish in colour. Nice field with the binoculars. No averted vision required.

Seeing: 5 <1-10 Seeing Scale (10 best)>. 
Location of site: Annen, The Netherlands - 53N, 6E
Site classification: Village backyard
Sky darkness: 4.5 <Limiting magnitude>
Bino: Leica 10x42 Trinovid, semi-handheld
Magnification: 10x
Bino observing doesn't do justice to this beautiful double. I can be seen and split, but is a bit faint and shows as an average double.
With the C11 however this is a real showpiece. The colors are beautiful, yellow and blue. I gave this one a rating 2 for the C11 on another occasion, now I will promote it to rating 1.
Rating: 3

Location of site: Lake Oswego, Oregon

Dim double near the threshold of perception on this moon lit evening.  Definite though dim separation. The double forms an equilateral
triangle with Beta and Gamma Lyrae.

Both the binocular list and the Astro League list have this double as STT 525.  Checking the WDS, I believe it is more properly SHJ 282 AC.
